The Pyramid Texts is the only thing that survives from the era. Egyptology pretends there is extensive evidence and writing left by the great pyramid builders but this is wholly false. The little that actually survives is just lists and labels and none of these support their assumptions and numerous ones are totally at odds with the assumptions. They had weigher rekoners, boat crews, overseers of canals, scientists (mistranslated as phophets), boat overseers, and metal workers here and there's no evidence of ramp builders, stone draggers, or any menial way to build.

The Pyramid Texts was ancient when it was inscribed into pyramid walls after the end of the great pyramid building age and they distinctly, repeatedly, and coherently say not only that the gods built them but exactly how as well. They said the earth is high under the sky by the means of Tefnut. They said Osiris tows the earth by means of balance. All the evidence they left is fully consistent with this including the five step great pyramids along whose steep sides they lifted the stones one step at a time.
